Hello folks. My first post on this Forum:
I have a conundrum, I have built a LED light fixture in my living room. The issue I have is that the LEDS have dimmed over the last 5 months by about 50%. I did not notice it until I had to replace one the other day, and it was way brighter then the existing ones. (tried 2 new ones to be sure).
My setup is a simple one,
110/120V AC input
Through a DC rectifier
into 42 LED's in series
Each LED is using about 2.7 volts.
The LED's were bought on EBAY, and are 5mm White LED 18000mcd 20mA 3.2-3.6 Forward Voltage (from China)
I thought this would be an ok setup, but as I mentioned, they are getting dimmer.
Any ideas why?
Thanks in advance!
Edward.
